T0 ctZZ whom it may concern.-

Be it known that I, Huoo R. KUERsTEN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a sofa-bed, the object being toprovide a device of this description which can be adjusted to its various positions by the movements of seat and back; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective view of a sofa-bed constructed in accordance with my invention. Fig. 2 is a detail sectional view, on an enlarged scale, showing the hinge pivotally connecting the seat and back in the position in whichthe back is held in its upright position. Fig. 3 is a similar view showing the back thrown slightly forward preparatory to bringing it to a horizontal position to form the bed. Fig. 4 is a similar view showing the back brought down almost to the horizontal position. Fig. 5 is a similar. view showing the back in its horizontal position. Fig. 6 is a detail view in elevation, illustrating the form of the guide on one of the hinge members prior to mounting it thereon. Fig. 7 is a rear elevation of the seat member of the hinge, showing the manner of limiting the movements of the lug for retaining the back in its upright position.

Referring now to said drawings, A indicates the box portion of a sofa-bed, upon which the seat portion B and back portion 0 are supported, all of said members being pivotally connected with each other by means of a hinge D, having three leaves er, I), and 0, one of which is secured to each of said members A,'B, and G. Said member a of said hinge D consists of a rod or standard rigidly secured to the base portion A and supporting said members B and O, to which the leaves I) and c are secured. The latter consist eachof a flat plate having a projecting tongue, through the end portion of which the pivot passes, the tongue of the member I) being slightly offset to bring the main portions of the members I) and c in the same plane.

' In the lower rear corner portion of the member b a lug d is pivotally mounted, which is adapted to engage and be engaged by an arm E, pivotally secured to the lower rear corner of the member 0. Said lug dis provided with two ears 6 and f, which are adapted to be engaged by projections e and f. on said arm E to turn said lug to opposite limits of its movement, and said ear f being adapted to enter and engage a recess 9 in said arm E to limit the motion of said member 0 in one direction. Said lug 01 carries a projection h, adapted to pass through and engage the Walls of a slot e' in said member I) to limit the motion of said lug. Said arm E passes through a guide F, mounted'on said member b and consisting of a metal strap offset at its ends to form a raised middle portion, between which and said member I) said arm E passes. One of said ends of said guide F is offset to a less extent than the other end thereof, said less-offset end being adapted to rest upon said lugd and secured by means of the rivet forming the pivot of said lug, while said other end of said guide F is riveted directly upon the member 19. In order to prevent free movement of said lug b, said guide F is so formed as to act as a spring bearing heavily upon said lug, this. being effected by forming the guide so that its less-offset end is inclined upwardly. The said end is then first secured in position and the other or greater offset end then forced down and secured to said member b. In this manner the less-offset end will obviously bear heavily upon the free end portion of said lug d, and thus cause same to be hindered in its motion. As before stated, the ear f of said lug d isadapted to enter and engage a recess 9 in said arm E to limit the movement of said member a in one direction, or, in other words, supporting said member 0 in a raised position, and said member 0 carries the back portion 0, supporting the latter in the position shown in Fig. 1 to form a sofa. The said recess 9 is situated adjacent the projection e of said arm E, at the free end thereof, so that said projection e is adjacent the ear 6 of said lug (I, while said back C is held in its upright position. Then it is desired to lower the back 0 to transform said sofa into a bed, the same is first moved forward, as shown in Fig. 3, thereby withdrawing said recess 9 from said ear f and likewise bringing the projection e into engagement with said ear 0, thereby turning said lug to the rearward limit of its motion and throwing said ear f out of the path of said recess g. The movement of the back C is then reversed and same lowered to its horizontal position. During this movement, however, and when reaching the position shown in Fig. at the projection f of said arm E is brought into engagement with said ear f, and by continuing the motion of the back 0 until the horizontal position is reached said projection f returns the lug d to the forward limit of its motion. The sofa is then in position to be used as a bed, the base portion A serving as a receptacle for the beddin To get the bedding, it is now only necessary to raise the seat portion 13, which is free to move, and by raising same until said ear f engages the recess 9 the seatwill be supported in a vertical position while the bedding is being removed. To then return the seat to its horizontal position, it must be forced rearwardly to throw the ear 6 into engagement with the projection e to return said lug d to the rearward limit of its motion. The seat can then again be lowered, and as it approaches its horizontal position said lug d will again be turned to the forward limit of its motion, as will be obvious.

Instead of following the above routine the operator may also lower the back by raising the seat and leave the seat raised until the bedding has been taken from the base portion and then lower the seat, as above. To return the back to its upright position, the same may be directly raised, or it may also be done by first raising the seat, thus uncovering the base to permit the bedding to be returned, and then lowering the seat without first moving it rearwardly, thus retaining the lug din engagement with the recess 9 and causing the back to be raised while the seat is being lowered.

My device is extremely simple and durable in construction and is very efiicient.

I claim as my invention- 1. In a sofa-bed, the combination with a base portion, a seat portion and a back portion, of a hinge common to all of said portions and connecting same pivotall y together, said portions of said hinge secured to said seat and back portions respectively carrying a pivoted lug provided with ears and an arm having projections and a recess adapted to engage the ears of said lug to turn said lug to opposite limits of its movement, whereby said seat and back are alternately locked together at an angleand released, said arm and lug being actuated by the relative movements of said seat and back.

2. In a sofa-bed, the combination with a base portion, a seat portion and a back portion, of a hinge common to all of said por tions and connecting same pivotally together, said portions of said hinge secured to said seat and back portions respectively carrying a pivoted lug provided with ears, and a pivoted arm adapted to pass over said lug and provided with projections adapted to engage said ears of said lug to turn the latter to opposite limits of its movement, and a recess in said arm adapted to be engaged by one of said ears of said lug when the latter is at one limit of its movement to lock said seat and back portions together at an angle, said lug and arm being relatively actuated by relative movements of said seat and back portions.

3. In a sofa-bed, the combination with a rigid base portion and seat and back portions pivotally mounted thereon and movable with relation to each other, of an arm pivotally secured to one of said last-named portions and provided adjacent its, ends with projec tions, and a recess between said projections, and a lug pivotally mounted on the other of said portions and provided with an ear adapted to engage one of said projections of said arm and the recess therein, and an ear adapted to engage said other projection on said arm, said lug being adapted to be turned in oppo site directions by said projections to alternately throw said first-named ear into and out of the path of said recess, whereby said seat and back portions are alternately locked together at an angle and released, said arm and lug being actuated by relative movements of said seat and back portions.

4. In a sofa-bed, the combination with a rigid base portion and seat and back portions pivotally mounted thereon and movable with relation to each other, of an arm pivotally secured to one of said last-named portions and provided adjacent its ends with projections, and a recess between said projections, and a lug pivotally mounted on the other of said portions and provided with an ear adapt ed to engage one of said projections of said arm and the recess therein, and an ear adapted to engage said other projection on said arm, said lug being adapted to be turned in opposite directions by said projections to alternately throw said first-named car into and out of the path of said recess, whereby said seat and back portions are alternately locked together at an angle and released, and means for limiting the motion of said lug, said arm and lug being actuated by relative movements of said seat and back portions.

'5. In a sofa-bed, the combination with a rigid base portion and seat and back portions pivotally mounted thereon and movable with relation to each other, of an arm pivotally secured to one of said last-named portions and provided adjacent its ends with projections, and a recess between said projections, and a lug pivotally mounted on the other of said portions and provided with an ear adapted to engage one of said projections of said 5 arm and the recess therein, and an ear adapted to engage said other projection on said arm, said lug being-adapted to be turned in opposite directions by said projections to be alternately locked together at an angle and rere leased, means for limiting the movements of said lug, and a spring bearing upon said lug and adapted to hinder the free motion thereof, said arm and lug being actuated by relative movements of said seat and back.

In testimony whereof I affix my signature I 5 in presence of two Witnesses.
